Angular.js: How can I return a content without view? Returning atom feed to users

Question

I plan to generate an Atom feed inside my AngularJS controller. A want to generate a view, but not on the server-side, because I want to replace the URI with a new AngularJS route.

Now I know how to write XML with JavaScript, but I have no idea about how to returning a XML content without a view.

My route setting is quite normal like below. It uses templateUrl to render a partial view.

.when('/posts', {
            templateUrl: 'theme/post_list.html',
            controller: PostsController
        })

Is it possible to serve XML content without a view using AngularJS? Like so:

.when('/posts.atom', {
            controller: PostsController
        })

Generating the angular.js routed Atom feed on the server-side is possible, but I don't want it.

Use the following process:

• Append an <object> or <iframe> to the DOM with the XML within the tag

OR:

• Return Atom from the service

• Store in a documentFragment

• Use transformToFragment or DOMParser to create a view

• Use XMLSerializer to convert the view to a string

• Insert an XML stylesheet into the string:

    <?xml-stylesheet href="feed.css"?>
  

• Use the string as the value of the srcdoc attribute:

    <iframe srcdoc="{{atomfeed}}" height="95%" width="100%">
  

For example:

$scope.atomstyle='<?xml-stylesheet href="feed.css"?>'
$scope.atomboilerplate='<feed xmlns="http://www.w3.org/2005/Atom">'
$scope.atomhead='<title></title><link></link>'
$scope.atomcontent='<entry><title></title><link></link></entry>';
$scope.atomtail='</feed>'

$scope.atomfeed=String().concat
 (
 $scope.atomstyle, 
 $scope.atomboilerplate,
 $scope.atomhead,
 $scope.atomcontent,
 $scope.atomtail
 )
